Phenom 9500...can't overclock hardly, and problems when higly stressing out at stock settings:

Phenom 9500
2x2GB G.Skill 800mhz = 4GB
GIGABYTE MA790FX-DS5 board
Zalman 9500 (giant fan)
x1950PRO 512MB Power Color Vid Card

At stock settings: (optimized defaults in bios)
I ran the OCCT stress tests...first one auto (which is both CPU and Memory i'm guessing) and BSOD both times in 12-20 minutes out of 30 minutes (error:a clock interupt was not received on a secondary processor within the alocated time interval). BSOD while these tests were running and i was opening another program / app.

Then the third time I ran it on just memory it was fine, then i ran it again on both mem and cpu and worked just fine, then i ran it for 5 hours on both CPU and Memory just fine (note: let the stress test run without intefering with the computer)

....then i really stressed it by running AMD Overdrives bench util, prime 95, and OCCT....that completely hard locked up with no BSOD in about 10 minutes.

Note: I ran memtest86+ of a bootable disc and let it go through almost 1.5 passes (about an hour of testing) memory came out fine, error free. Tried removing one stick, tried swapping the sticks, bsod was still present, so i'm confident it's not the memory.

overclocked fsb to 210:
The same BSOD error as soon as it booted up varying from a few seconds of loading bar of vista, to about 2 minutes into OS. At this point i'm concluding it's related to either the processor or the mother board....playing with the HT from Auto, 1.2, 1.4, 1.6, 1.8, 2.0 (FSB), I was able to get into varying stages of how far into windows i could get before it BSOD'd. Even played with the HTT(Hypter Transport Transmit) volt and HTR (Hyper Transport Receive) voltage {0,+0.05}, {.05, 0}, {+.05,+.05} ...BSOD came even faster playing with the voltages... even incremented the CPU voltage 1 step at at time and rebooted a few times upping it each time with no luck.

In conclusion ...BSOD shows on stock settings running multiple stress tests and/or doing something simple while the stress test is going, such as opening another application in some instances)... raising the FSB makes the error much more prominent that it barely gets into windows fully if it even makes it that far. At FSB 205, and most notably at FSB 210.

Do I have a POS (Piece Of *****) processor? Your thoughts? Anyone?

Thanks, Dave.
